cross-compile/mingw: comment on sigrok specific "MXE fixes" patch

No change in behaviour, just comments and grouping and whitespace fixup.
Separate the binutils downgrade from the glib downgrade. Provide empty
lines for faster editor navigation. Provide comments for human readers.
Keep MXE's style of glib.mk indentation when disabling warnings.

This patch no longer applies to recent MXE versions, but might as well
have become obsolete. A build without these "MXE fixes" patches is
attempted, the result is yet to get determined. Needs more consideration.

+Implementor's note: These patches currently (2022-11) don't apply to
+recent MXE, their context has changed. The patches' motivation might
+have become obsolete, too. This needs reconsideration. When in doubt,
+attempt to build with an MXE toolchain which omits these "MXE fixes"
+(which actually are downgrades of tools and libraries, while mainline
+MXE has upgraded and could have fixed previous issues). Older notes
+from a previous implementation follow below.

+
 These patches are currently required to get a properly working
 MXE setup for sigrok usage.
